Michelle Obama makes her official entrance on the 2010 campaign stage in Milwaukee on Wednesday, but is expected to keep politics at arm’s length and emphasize her role as “Mom-in-Chief.”

"...This isn't something I do very often," Obama is expected to say at a fundraising event for Sen. Russ Feingold, according to prepared remarks obtained by POLITICO.

"As a self-described Mom-in-Chief, my first priority in the White House has been making sure that my girls are happy and healthy and adjusting to this new life," the first lady will say. "Like every parent I know, my children are the center of my world. My hopes for their future are at the heart of every single thing I do. And that's really why I'm here today."

In the remarks—which are expected to run approximately 20 minutes — Obama will attempt to personalize issues like the faltering economy and poor schools.

While she is not expected to address her husband's critics on the economy—an issue that has plagued the administration— she will express her sympathy for the struggles of every-day Americans.

She will say that she sees the economic hardship "in the child whose mom has just lost her job and worries about how her family will pay the bills.” And she will pivot to the hardships military families face: “I see it in the child whose dad has just been deployed and tries so hard to be brave for his younger siblings."

As Obama hits the stump on what will include a seven-state, cross country fundraising tour, she will highlight her husband’s accomplishments and the agenda he is "fighting for," according to aides, while attempting to rally voters behind specific candidates.

The first lady will also stress how the nation is "beginning to turn a corner" and will tout White House reforms such as health care.

Last week, Obama kicked off her foray into the midterm elections by holding a call with thousands of supporters.

“We’re just beginning to see the results of our work,” Obama said on the call. “So don’t stay home. Don’t let frustration keep you from voting.”

While the first lady won't be traveling on weekends so she can spend time with her daughters, she is expected to add more outreach calls to her schedule in the lead-up to the election, White House aides say. , adding that those calls will target women and young voters.
